OpenWRT rocks...

I'm sure most people here should know about OpenWRT, it's a router framework based on embedded Linux that runs on many appliance routers. It's an extremely flexible solution that lets you include packages for most features you'd need.

I was playing with PiHole and somehow broke DNS on my router. I looked for a recent backup from before the changes, but I'd deleted it. Drat.

What I was able to do was scp into the router and copy the /etc/config directory to my desktop, then do a hard reset. Once it reset, I configured the wireless, then copied the firewall information and static leases from my desktop and I was mostly there.

Then, did a backup. I'll start doing that from now on before changes.

One other cool thing with OpenWRT - I'm running two Linksys WRT1900ac routers. They have dual flash ram areas. You flash one "side" with OpenWRT, and if you brick it, try booting it 3 times and it'll flip to the other, working side so you can try again. So, you can either keep the OEM linksys firmware on one side, or OpenWRT on both, and upgrade one side at a time.

It makes them "Unbrickable", at least as far as I've tried. :)
